Abstract

L'effuent réactionnel sortant d'un réacteur d'oxydéshydrogénation utilisé dans la préparation du tertio-butylstyrène à partir de tertio-butyléthylbenzène est soumis à une distillation extractive (2) avec du sulfolane pour séparer du tertio-butylstyrène la charge du réacteur n'ayant pas réagi. Le tertio-butylstyrène est un composé à usages multiples, par exemple, comme composés chimiques intermédiaires, monomères ou comonomères dans la production de polymères, etc.
